Load .env file in Bash

There is an easy way to load an .env file in #bash. Let’s have example .env file:

example=value
example2=value

then you can read this file in #bash like this:

#!/usr/bin/env bash

set -o allexport
[[ -f .env ]] && source .env
set +o allexport

Warning: All existing variables are overridden by .env content.
